Freeze PC using a hard reset due to a faulty CPU.
Freeze PC using a hard reset due to a faulty CPU.
Recently I upgraded to a low-cost PC using an Xeon 5687 (previously i7-920), 16GB RAM (originally 8GB) and a cooler from Intel. After several attempts, I set the OC CPU to 4.2GHz and increased its voltage, thinking it would improve stability. Initially, I started with 1.5V for OCCT but stopped after two minutes. Then I reset the PC and lowered the voltage to 1.4V (keeping under Intel’s VRM max of 1.35V). Eventually, I gave up on OC because the CPU overheated during OCCT in just three minutes. Later, a random issue occurred within an hour: the system froze or hung, losing mouse, keyboard, and headphone connections until a hard reset. After restarting, I didn’t see any freezes unless the PC was off for hours.
Key questions:
- How likely is this problem due to CPU damage from a 0.15V overvoltage?
- Are there tools to monitor performance or save data to verify if the issue came from the CPU or RAM?
